Image illuminating device for use in e.g. offset printing plate, has light sources whose pixels lie along pixel line, where pixel line has tilting angle for illumination of image in standard size and tilting device changes tilting angle

摘要

The device has a set of individually controllable light sources (20), where equally spaced pixels (30) of the light sources lie against a printing plate (12) during simultaneous controlling of the light sources along a pixel line. The pixel line has a tilting angle (32) across from a slowly scanning direction (18) for the illumination of an image in a standard size, where a tilting device (34) changes the tilting angle. Independent claims are also included for the following: (1) a printing device typesetter with a device for illuminating an image (2) a printing device with a device for illuminating an image (3) a printing machine including a printing device with a device for illuminating an image (4) a method for illuminating an image.
